| + | There are many options for NFS and I want to keep this article short but effective so I am leaving out many of the various configuration items that you could do. However there is one option that is worth mentioning, **no_root_squash**. By default NFS will downgrade any files created with the root permissions to the nobody user. This is a security feature that prevents privileges from being shared unless specifically requested. | ||
| + | If I create a file as the root user on the client on the NFS share, by default that file is owned by the nobody user. | ||
| + | <code> | ||
| + | root@client:~# touch /shared/nfs1/file2 | ||
| + | root@server:/nfs# ls -la file2 | ||
| + | -rw-r--r-- 1 nobody nogroup 0 Nov 18 18:06 file2 | ||
| + | </code> | ||
| + | Sometimes it is important to share files that are owned as root with the proper permissions, in these cases this can be done by simply adding the **no_root_squash** attribute to the **/etc/exports** configuration. | ||
| - | + | **Edit the /etc/exports file:** | |
| + | <code> | ||
| + | /nfs_share 192.168.1.1/24(rw,sync,no_root_squash) | ||
